TX Power Control for 5 GHz

5 GHz power control is done via Image Creator where the maximum transmit power is provided (5). Within Image Creator power control is possible per channel, region (6), and modulation rates (7). In addition, it is possible to enter an additional back-off (8)factor per channel and modulation rate for further margin to regulatory requirements.

Finally, it is also possible to set the TX and RX trace losses to the antenna per band (9). The peak antenna gain (10)can also be provided, thus allowing further control. For a full description of options and capabilities see Uniflash with Image Creator User Guide.


The maximum transmit power range is 18dBm to 0.125dBm in 0.125dBm decrements.
FCC/ISED, ETSI (Europe), and Japan are supported.
Rates are grouped into high modulation rates (MCS7, 54 OFDM and 48 OFDM) and lower modulation rates (all other rates).
The back-off range is 0 dBm to 18 dBm in 0.125 dBm increments, with the maximum back-off not exceed that of the maximum transmit power.
The range of losses if from 0 dBm to 7.75 dBm in 0.125 dBm increments.
The antenna gain has a range of -2 dBi to 5.75 dBi in 0.125 dBi increments.
